I'm a mechanical engineer with over 30 years of designing machines utilizing electro-magnetic radiation (UV, IR, X-RAY) and convection/conduction energy transfer. I have real world experience in making things work, not just theorizing (& that is a huge difference). I can tell you that the cause of temperature changes on earth are due to the massive unshielded thermo-nuclear reactor about 9 light minutes away from us.
I also have designed hundreds of temperature control systems and to be serious the tight control band the earth has is pretty amazing.
Of course, the average super genius of the left will think they know more than I because they read some slanted article by a journalist that can't understand why their steering wheel gets hot on a sunny day in the winter.
